Fresh Air Exchangers

Lennox Heat- and Energy-Recovery Ventilators

Whole-home ventilation systems designed to improve air quality and comfort.

Air to Air Heat Echangers

According to the Environmental Protection Agency (EPA), the air inside the average home is up to five times more polluted than the air outside.* This problem can be even worse in today's tightly sealed homes, because pollutants have no way to escape. A Lennox heat- or energy-recovery ventilator (HRV/ERV) improves air quality by improving the flow of air. Using advanced dual-chamber technology, these systems exchange stale air from inside your home with fresher outdoor air.

Fresh Air For a Cleaner, More Comfortable Home

A Lennox HRV or ERV system lets you enjoy the fresh-air feel of an open window, with virtually little or no heat or energy loss. That's because these systems work continually to provide the best possible balance of indoor and outdoor air. They draw just the right amount of air from outside, recovering heat and energy from inside, to ensure that every corner of your home is comfortable.

To ensure proper air quality, the average home should have at least .35 ACH (air changes per hour). Many newer, high-efficiency homes have an ACH rating as low as .05, which can lead to an unhealthy buildup of moisture and pollutants. A Lennox HRV or ERV (pictured above) provides a simple and economical way to freshen the air.

Energy Recovery Ventilator - ERV

  • Desinged for warmer, humid climates
  • Reduces the humidity in the fresh air supplied to the home
